12 Claims.

invention has for its object an improved machine. tool adapted to surface very. broad parts andV in particular blocks of. metal` before and after their passage through the blooming..

rolling mill in rolling plants and also platesk of. light metal. any alloys, suchv as aluminium, aluminium alloys known.. under the name of Duralumin andthe like. Heretoforethis surfacing was executed on a planing machine or on a milling. machine, such asa milling. and planing machine, through a successioni of. cuts.- Such an operation on aplanerisnot an economical one as the best planing machines. on the market allow only cutting, speeds of. 100` meters per minute Whereas aluminium may be machined at cuttingspeedsas high as 1500 meters per minute.

In. the present. state of the art it is not possible to provide planingV machines operating even.

at cutting speeds. of. 300.meters. per minute.

Operation on a milling machine of the milling.A and planing machine type operating through a. succession of cuts, although of. a much higher. eiciency. than the planing, operation, isnot economical. As a matter of fact for. surfacing. for instance a plate two meters broad with a cutter the diameter ofA which is about. 550.. mm., it-ishorizontal. cross-beam underneath which the work-carrying table is. adapted.. to more, said beam including recesses Within which may slide onthe one hand-operatingunits constituted each.

by av tool and its. control motor. andthe otherv hand supporting columns. for, a. movable cross member. carryingV theabove-mentioned operat. ing units.

According to a; further. feature. of. my invention the above mentionedoperating. unitsrmay.

on the one hand. be.. adjusted separately. with.

reference toene another on the movable crossmember and. on. the other. handA theyA may be` moved as a unit rigid with said movablevcrossmember.

Other. features.; of.' the. invention. will. appear;

in the reading of the followingr description of an. embodiment of my invention chosen by way of;r example and illustrated diagrammatically in. accompanying drawing.

In said drawing:

Fig. l is a view in elevation of a machine embodying my invention.

Fig. 2 is a side elevation as viewed from the right in Fig. 1.

Fig; 3 is; a plan view of the machine of Fig. 1.

Fig. 4 is a cross-sectional'view of an operating uniti` adapted for use in such a machine.

Figs. 5 and 6 are cross sectional views taken. respectively on 'lines VP-V' and'VI-Vlot Fig. 1.

The machine executed iny conformity with my invention andas illustrated in accompanying drawings comprises a bed lad'apted to carrya table 2 and to` guide it during#itsdisplacementsto: and froV on1 saidV bed; Said table 2 carrying theworlcmayslide-longitudinally over the bedl l-'byvirtue-of the-usualI means for guiding andi driving. used in most standard machine tools, such-as guiding upon square, V-slnaped,` dove'- taileel strips etc., driving through pinion and" rack, leadingV screw and nutg. through hydraulic, electrical-and the like devices,Y etc. f

At.. each; side of the. bed l` are arranged. twol uprights. 3a andI 3b rigid-x withK said bed andadapted to carry a horizontal cross-beam'- 11t rigidly secured to the upper end of the uprights 3a and 3b.

'Ilhis str-ucture including the bed, uprightsand' cross-beam-forms a unit.providedwith a veryA high rigidity and capable of. resisting. under.v extreme. conditions the verticalY andv horizontalv forces and their components producedby oper-ation.

The horizontal cross-beam 4 is'provided. with. a plurality. of. cylindrical. recesses. 5a?. 5b, 5c, 5d, in Fig. 6,.adapted to guide a corresponding num.- berof operating; units Sa, 6b, 5c, d,.Figs. l and 3.., Theoperating unitsmay` slide withinthe re-' cessesthus provided throughthe cross-beamd.. To. this end. they may be-secured.. in a movable cross member l: which is carried by two columnsV The units 6d, 6b, 6c, Sd'also may be slidablyl ing all of the units as a rigid whole together with the cross beam l. This arrangement forms one of the main features of the present invention.

The columns Ba and 8b, and the operating units 6a, 6b, 6c, 6d may be rigidly fastened in the stationary cross-beam 4, after being slidably moved to a desired position, by means of suitable locking members. The omission of said locking means would, however, not change the general arrangement according to my invention, as such locking means may serve merely for removing the play due to an insufficiently accurate machining of the sliding recesses.

Nevertheless, I will disclose now by Way of example a possible form of such locking means.

A lever 9 may rock upon a stud Ill under the control of an electromagnet Il, these parts being carried by the cross beam 4. When the electromagnet is energized, it causes the shoe l2 of the lever 9 to bear strongly against the part to be locked, in the present instance the column 8a or 8b, which latter transmits the pressure to the bearing surfaces I3 and I4. These locking means may be controlled by a suitable lever l5 for actuating means to energize or deenergize said electromagnets il. Similar devices having levers 9 may be provided for locking the units 6a, 6b, 6c, 6d in the cross beam 4.

Similar locking devices (not shown) controlled by a lever I6 may also be used for locking the operating units 6a, Eb, 6c, 6d to the movable crossbeam 1.

Lastly such locking means may be used for the columns 8a and 8b carrying the cross-beam l, said locking means being controlled in a similar manner by a suitable lever I1 so as to lock the cross-beam 'l in its adjusted position.

When the columns 8a, 8b, thus have been rigidly fastened in the cross-beam 4, it is possible to unlock the operative units with reference both to the stationary cross-beam 4 and to the movable cross-beam 1, by means for instance of the levers l5 and I5, and to raise or to lower through the hand-Wheel i8 the operating units one with reference to the other so as to bring the operating tools into a same plane or in different positions with reference to one another as required by the operation to be eifected.

When the operating units have been made rigid with the movable cross-beam 1 and are free to slide, together with the columns 8a, 8b, in the stationary cross-beam 4, it is possible by means of the control device I9 to move vertically and simultaneously the system of four operating units with reference to the plane of the table 2 in conformity with a` further important feature of my invention.

In Fig. 4, I have shown by Way of example one embodiment of the operating units 6a, Eb, 5c, Sd. In this example, 20 designates the tool which it is desired to move in a rotary motion. To this end it is fastened on a shaft 2l the lower end of which is carried by a bearing 22 the upper end being journalled in bearing 23. The shaft carries the rotor of an electric motor `the stator of which is shown at 25 and the frame at 26. At the upper end of the unit driving motor 21 is supported for driving the cooling fan 28.

These operating units 6a, 6b, 6c, 6d may however be constructed in any other suitable manner Without changing thereby the scope of the present invention. They may be of the individually controlled mechanical type or may be controlled simultaneously by a single shaft or they may be 4 driven by a belt running on a pulley keyed to the end of the shaft,

Similiarly it is possible Without changing the scope of the invention to replace the control electromagnet Il for locking the operative units as illustrated in Fig. 5 by a mechanical or hydraulic device or else by an electric motor or any other suitable control device effective to grip the units or the columns 8a, 8b.

In the same manner, it is possible to execute the locking means in a manner different from that disclosed by way of example in Figs. 5 and 6. Thus I may use locking means comprising a longitudinal Wedge, conical rings, pinching means and the like.

Moreover other modications may be made in the details of the structure of the machine described hereinabove and illustrated in the drawing Without the general principle of my invention being modified thereby. Thus, inter alia, the shape of the columns 8a, 8b and of the operating units 6a, Bb, 6c, Gd may, instead of being cylindrical, assume a different shape such, for instance, as a prismatic shape With any desired number of lateral surfaces. It is also possible to modify the number of operating units incorporated in the machines, which number may be different from that of the embodiment shown and described by Way of example.

It will be understood that the cutter 20 may be replaced, depending upon the Work to be executed, by any other suitable tool.
